I realise my earlier email was imprecise. I am mostly lamenting the
mis-feature (IMO) that labels get evaluated as macros within the internals
of -graph- even though they are not even macros to begin with. Nor are they
passed as arguments by the user. Once a label is defined, it should always
continue to be treated as a string literal, i.e. no macro interpolation
should be done.
The SMCL work-around works only in ytitle() or title() options, it doesn't
work when setting variable labels, e.g.
. la var xrus "{c $|}US per {c $|}CA"
doesn't work the same way. It is not a serious nuisance but is still
unfortunate; it doesn't reward the overhead of having diligently labelled
one's data.
